Pearltone is a company established in 1929, specializing in water-repellent treatments. The company celebrates its 95th anniversary in 2024 and has decided to create T-shirts to mark the occasion.

Design proposals were widely solicited through the company's employees. As a result, for example, a certain kimono design office that has worked on costumes for Michael Jackson and Akina Nakamori , as well as designers from a textile company favored by the Imperial Household Agency, also participated in the design competition.

Ultimately, the design proposal shown on this page was selected based on the judgment of the company's management. This proposal illustrates the phenomenon of water droplets jumping on a water-repellent surface.
